Abstract: The present invention discloses a device for solid-state fluidization mining of seabed shallow layer non-diagenetic natural gas hydrates. The device comprises a hydraulic jet nozzle set, a coiled tubing, a hydrate collecting ship arranged on the sea surface, a transfer station arranged in sea water and a riser arranged in a seabed surface layer. A guide seat is arranged in the riser. The hydraulic jet nozzle set is arranged in the guide seat. A delivery pipe connected with the transfer station sleeves a nozzle body. An opening is formed in a position where the delivery pipe is in contact with the nozzle body. The transfer station is connected with the hydrate collecting ship. The present invention further discloses a method for collecting seabed shallow layer non-diagenetic hydrates.

Abstract: The present invention discloses a downhole automatic connection device for an oil pipe internal communication cable for intelligent layered water injection. The connection device comprises a water injection pipe string in which a cable lowering mechanism is arranged. The cable lowering mechanism comprises a cable, a cable female connector, a motor and load-bearing blades. The cable female connector comprises a female connector shell, a jack insulating plate and an electromagnet. A cable male connector is also fixedly arranged in the water injection pipe string. The cable male connector comprises a male connector shell, a pin insulating plate and an NdFeB magnet. A pin wire welding point is electrically connected with a sensor on an intelligent water distributor. A lead arranged in the pin insulating plate is connected between a pin and the pin wire welding point. The present invention also discloses a connection method.
